Well it's not figuring out the fraction that's the problem, I just divide to 
give me a decimal value (still in inches thoe) It's the standard system. It 
started because American wanted to be so different from the country they 
declared independance from that they even came up with a new form of 
calculations. It sucks. Metric is so much easier, everything really should be 
metric, everyone I've spoken to pretty much agrees except the hardcore 
patriots. I just don't care for measuring something in fractions, converting 
it to decimal, and then converting it to metric. It's pointless when the 
whole world uses metric, and we are the only country who doesn't. It really 
makes us and our equipment "Incompatible" in a sense. While I was building my 
ROV I used standard, and now that most of the equipment I want to buy fits up 
with metric, I now know what I'm going to use for my sub. It just makes it 
that much more easier, you know?
